JPOWEB-BBAKE FOR AUTOMOBILES.'

't'o all whom it may concern:

Be it known that I, GEORGE J. CLAY'roN, a citizen of the United States, residing at Lakewood, in the county of Ocean, State of New Jersey, have invented'certain new and useful Improvements in Power-Brakes for Automobiles; and I do hereby declare the following to be a full, clear, and exact description-of the invention, suh as will euable others skilled in the art to which it apj pertains to make and use the same.

his "invention relates to automobile brakes and has for an object to novel cam meansfor operating a cone nut clutch, this means being driven from the the rear axle and being pedal. A second object of the invention is to provide novel spring controlled locking means for holding the pedal depressed when desired.

\Vith the above objects in view the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor dots-1s of'construction within the scope of the appended claim.

'In the accompanying drawings forming part of this specification z Figure 1 is a plan [view of an automobile chassis with portions broken away and showing my improved brake mechanism assembled therewith. Fig. 2 is a longitudinal srctional view takenpn the-line-2-2 Fig. 1:'=--f' Fig. 3'is a cross sectional View taken on the line 3 3 Fig. 1. Fig. 1 is a detail cross sectional view taken on the line 4[ l Fig. 2. Fig. 5 is a detail perspective view of the pedal locking mechanism.

Referring now to the drawings in which like characters of reference designate similar parts, 10 designates in general the automobile chassis, 11 the driving shaft, 12 the rear axle carrying the usual difierential gear 1.8, and 1 1 the rear wheels.

The wheels clutch memberlfi having a conical opening 16 into which slides'a cone clutch member 17 that is slidably mounted on the axle 12.

20. The rods 18 of both cone clutch members are offset near the inner ends in order to'elevate the concave head members above the-difiierential gear casing as clearly shown in F 1g, 3. Helical springs 21 are seated on the'rodsandserve to hold the cone clutch members out of engagement with the mating clutch members. A cylindrical casing 22 encircles and houses each mating cone clutch member 17 and clutch member 15 so that dustand other foreign matter is prevented from entry between the working faces of the members.

For sliding the cone clutch members into operative position, I provide a substantially egg shaped cam 23 the long axis of which extends in a vertical plane, this cam being carried upon the end of a stub shaft 24 which is journaled in a suitable bearing 25 and is provided with a friction gear 26 that is adapted to mesh with a clutch pinion 27 carried upon a spring controlled stub shaft 28, the clutch pinion 27 being in turn adapted to mesh with a friction gear 29 carried upon the driving shaft 11. The stubshaift 28 is provided remote from the clutch pinion with a disk head 30 and seated on this shaft between this head and the bearing 31 of the shaft is a helical spring 32 which normally serves to hold'the pinion heads disengaged. Upon pressure being exerted upon the disk head 30, the pinion is slid into engagement with both of the gears 29 and 26. Upon rotation of the shaft 24, the cam 23 will be rotated until the long axis extqnds in a horizontal plane and in this positron of the parts the cam will-bear against and force outwardly/the concave head 20 and hold the cone clutch members seated in the related clutch members. i

For actuating the brake, the bralre pedal 33 is connected to one leg of a pivoted angular lever 34 through the instrumentality of a connecting rod 35, the angular lever bearing against the disk head 28 of the clutch pinion shaft and moving the clutch pinion into operative engagement with the friction gears 26 and 29, upon depression of the pedal. Upon release of the pedal, the helical spring 32 of the clutch pinion and helical springs 21. of the cam clutch member rods operate to return the parts to inactive position.

In order to hold the brake applied in going down grades and under other conditions of service, I provide anotch 36 in the mobil 1? e01 nizers'i' gv-Jgar casing 3'? WHI'GST) is J by bolts Sliflably 5%- in L m a irigger 39,, a spring 429 1 semi-mi a) asmg in rear of 53m 11m; gm 5;
